[Elecraft] Elecraft night in Rome !
Hi, last night at the Rome local ham radio club me and Luca IZ0FYL we organized a Elecraft session with a presentation and a live test of Elecraft K3 (#4777 mine..) and K2, KX1 and T1 Tuner (all from Luca FYL). More that 25 local ham attended the event and they had test live the radio, all connetted to a antenna switch and to a windom hf wire antenna. We compared also a Icom 756pro3 with my K3 again using a simple antenna switch. There was much curiosity about Elecraft Radios.. many had never seen a K3 in real :-) Best 73 de IW0HK Andrea p.s. here is a photo of Luca IZ0YLF talking about using a K2 in CW: http://img15.imageshack.us/img15/568/k3ariroma.jpg -- Andrea Borgnino IW0HK - HB9EMK http://www.mediasuk.org/iw0hk http://www.mediasuk.org/archive http://www.biciurbana.org http://iwohk.tumblr.com/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Lock P3 frequency range independent of K3
Hi All, This is an aspect of the Orion II which beats the present K3. When one tunes the VFO the display remains steady for a period of time and the cursor moves across a frozen display in sync with the VFO. Once one stops tuning the VFO the display is no longer frozen. It does help in manually tuning the VFO rather than using the cursor to move to a different point in the displayed spectrum. I would like to see this change introduced. Boy oh boy a company which improves previously sold product! 73 Doug EI2CN -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Amateur Radio Operator N5GE Sent: 11 November 2010 00:53 To: Elecraft@mailman.qth.net Subject: Re: [Elecraft] Lock P3 frequency range independent of K3 My vote is NO...

The defacto mode of draging and skewing the waterfall makes it unrecognizable, losing track of and tune to a new target QSO up the band. It would seem much easier if tuning the K3 just moved a marker across an unmoving P3 display. My thoughts are towards operating next Field Day, where I might set the P3 to display, say, 7.025 through 7.075 KHz. Of course there would need to be a provision for re-centering the P3, most likely to a round number, not the actual K3 frequency. For example the P3 could re-set its center to the nearest frequency marker at the top of the the P3. As an example, assume a P3 set to a span of 50 KHz, where its 10 markers at the top would then be spaced 5 KHz apart. Assume a K3 is tuned to 7.048 KHz, and the re-center button is pressed. Consistent with the suggestion, then, the center frequency of the P3 would snap to 7.050 KHz, and display a span from 7.025 to 7.075 MHz. Besides the pile-up value another post suggests for this mode, I see it equally valuable for contests and for looking for an ongoing QSO. 73 Gary K6kV __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] P3 New LVL Cal Function (Beta 0.41)
Amateur Radio Operator N5GE wrote: Where do I find the instructions for using this feature? Al must have forgotten to include the instructions. The following is PRELIMINARY ONLY but should get you going: Amplitude Calibration The P3 comes with a default amplitude calibration that works well with a K3 transceiver that either was manufactured after approximately 9/1/2009 or, if an earlier unit, has the IF output buffer gain modification described in the application note on the Elecraft web site. If you have an earlier unit without the modification, or you are using the P3 with a different model transceiver, or if you just wish to obtain better amplitude accuracy on the P3 display, you can do the following calibration. The recommended test frequency is7040 kHz at a signal level of 50 microvolts (-73 dBm) using a calibrated signal generator such as the Elecraft XG2. However, any frequency and power level within the range of the transceiver and P3 display will also work. * Make sure the the P3 IF IN is connected to the transceiver IF output. If the transceiver is a K3, connect the RS-232 cable as well. Turn off the preamplifier and attenuator on the K3. If you have the KRX3 installed, make sure SUB is disabled. * Connect the signal generator to the transceiver antenna input. If it is a K3 that includes the KXV3 or KXV3A option, it is best to use the RX ANT IN connector to eliminate the possibility of damaging the signal generator if the K3 transmits accidentally. * Set the signal generator for 7040 kHz at a signal level of 50 mV (-73 dBm). * Set the SPAN on the P3 to 100 kHz, and tune the transceiver to approximately 7015 kHz so that the signal is centered on the right half of the display. Set the SCALE to maximum expansion (10 dB) and adjust the REF LVL to about -78 dBm, in order to place the peak of the signal about half way up the screen. You may notice a slight variation (~1.5 dB) in the peak signal level with small adjustments in the transceiver frequency, as the signal is tuned from pixel to pixel across the display. Adjust the frequency for a maximum reading. * Tap MENU, select Lvl Cal, tap the knob, and adjust the level calibration until the signal is at -73 dBm on the display. You can also calibrate a receiving or transceiving converter, either the K3's optional internal K144XV or an external device. If you plan to do the above calibration on a standard frequency, do it first since that calibration is added to the converter calibration. * Set up a signal generator, the transceiver and the P3 in a manner similar to the above to obtain a signal near the center of the right side of the display and approximately centered vertically, with the P3's SCAN at 100 kHz and the SCALE set to 10 dB. * Tap MENU, select XV Gain, tap the knob, and adjust the knob to select the desired converter band, 1-9.

Re: [Elecraft] Elecraft Digest, Vol 79, Issue 19
Hi all, at beginning of October I returned to Italy from Boston Airport.. After one month of stay in W2, W7 and W1 I collected a lot of rubbish for normal people eyes... Some stuff was in my two suite cases and by hand I carried two MFJ antenna analyzers for friends (in my hand carriage) and in a box (original) I hand carried an ATU donated by Art, K1GBX, to my radioclub (IQ7MU-Cassano Murge). I went very early to the airport to avoid rush staking problems. The carriage and box did not pass the TSA X-Ray check. The hand carriage was opened and with the two analyzers X-ray checked again. The ATU was removed from the box and also the foam holders removed, to avoid vison interference, and passed through the X-ray. I declared they all were amateur radio gadgets. No licence was requested to be shown. In Rome the ATU was scanned twice. Before sept 11, 2000, I was always carrying (in Europe and USA) a VHF rtx and a wire GP to stack on hotel windows and a home made 1/2 wave mobile antenna for mobile use, to be stuck on car windows ... never had any problem ... after such bad date ... I left everything at home... and had friends help, in W-land, borrowing mobile VHF rtx and antennas.

If you lock the P3 than the display will display from 7.000 to 7.050 for example (50KHz). From there, as you more the cursor and hit the QSY knob the little cursor line could change colors indicating it is working on that freq (and the rig has changed freq.) but the display doesn't have to change, it stays the same. The only thing that has changed is the color of the cursor, or just the fact that the rig is now parked at the new cursor location.

[Elecraft] Remote Operation on SSB with a K3 radio problem
I have successfully operated my home station while away from home on CW on and off for about a year. But would like to add the abilty to do SSB to my K3 radio and Computer. The computer running XP-Pro attached to the K3 has a good sound card in it but I don't know what hole I should be coming out of the sound card FROM ? Line Out? External Speaker out? And into which rear jack on the backside of the K3 radio? Mono line IN ? or Mic IN ? Do I also have to make up my cable then perhaps Stereo on the Computer end and into a Mono on the Radio end? I tried a Stereo to Stereo cable from a couple of the soundcard outputs into the Mono Line IN on the K3 but I could not come up with any settings for the Mic Gain and Antivox on the K3 that actually worked. They either wouldn't feed adequate audio to the radio or would ack the curciut and make the antivox act up tripping it all back off again. Guess I am somewhat lost. Sound back and forth between the home radio computer and me wherever I am is Microsoft program called MS Portrait which has worked flawlessly for both CW and with speakers hooked up I can also talk to people if someone is here at my home in the shack. Somewhat like being on a speaker telephone. It seems to work better than when I used IP-Sound. Normally these speakers are disconneted. If we are using the radio and would only be hooked up if someone were here for troubleshooting some problem. Also using a VPN to get to and from the computer using Ham Radio deluxe to control the K3 radio.

Re: [Elecraft] Remote Operation on SSB with a K3 radio problem
Hi John, I do some remote SSB operation (picking off DX when they don't show up on CW!), but I don't use VOX. Line out or speaker out (generically, the green jack) on your sound card to the line-in on the K3 with a standard stereo cable should work fine. I believe that the jack on the K3 is a stereo one, but the ring is not connected to anything. You will have to adjust the line-in level n the K3 to suit (I run mine somewhere around 20-25), and, as far as I know, this can only be done using the MIC control on the front of the K3 when MAIN:MIC-SEL is set to line-in. I've been meaning to bug Wayne about the fact that this can't be adjusted remotely, AFAIK, but once it's set about right, you can fine tune with the sound card's level controls.

Re: [Elecraft] K3 VGA info needed
I *will* split hairs - because a VGA cable has several pins tied to each other (the shields for the video signals I believe), and there are some pins that are not used. If one tries to use a VGA cable on the K3 ACC connector, the results may be disappointing. There are cables built with all 15 pins isolated and all pins populated, but they are harder to find. For clarity's sake, let's avoid referring to that connector as a VGA ACC connector or the DB-15HD female connector describe it well. 73, Don W3FPR On 11/11/2010 2:59 PM, Dick Dievendorff wrote: Bob: I don't want to split hairs, but the K3 ACC connector is not a VGA video connector.

Re: [Elecraft] [K3] Enhancement request - audio mixing
Barry, I may have misread the original question, but if all one wants to do is listen to the subrx in both channels, then it is possible by adjusting the mix settings, then turning the AF gain down on the main. That's what I do if I want a stereo type output from my sub receiver. This is helpful for those that have the bandpass filter installed only on the sub and they want to SWL with a second antenna connected to the aux input.

[Elecraft] KX1 Kit -- VFO Tuning and Readout ??
Question For you KX1 experts... I am in the process of building a KX1 and I am currently doing the Receiver Alignment as described on page 45 of the manual. I am stuck. I don't understand the VFO frequency readout. My KX1 is behaving differently then the description in the manual and I am not sure what kind of mistake I am making or if there is something wrong with the KX1 at this stage (although, all tests and functionality have shown to be OK up until this point). Here is the problem. The manual says (page 64) that when you tap the BAND button that the LED readout will the frequency, first showing the MHz, then KHz. Then, it says that L or U are added in LSB or USB modes. But, when I tap the BAND button, I get the MHz readout of 7 then I get two readouts following that as 080 and then 80.0 and only on this third number display is the decimal point lit up. Thus, tapping the BAND button displays 7, then 080, and then 80.0. Now, I can use the VFO Tune to adjust this final number but I am not sure why I am getting three numbers whereas the manual says that I would get two. Also, I don't see how to pick a particular frequency as the VFO Tune control and the LED readout do not seem to correspond in a manner that makes sense. So, I am missing something. For example, if the frequency were something like 7.058 then I would expect the first number to be 7, the second number to be 058. Can someone set me straight? 73, phil, K7PEH __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 mic gain and bias settings
Has anyone else noticed similar? I still haven't gotten a definitive answer, and am curious to see if others had experienced the same.

Can anyone confirm? 73 de James K2QI On Sat, Nov 6, 2010 at 7:54 PM, James Sarte k2qi@gmail.com wrote: Greetings Elecrafters, I previously posted a question to the group about mic gain settings in conjunction with the Elecraft MH2 hand mic. Prior to the slew of recent firmware updates, I had to set microphone bias to low, and keep the mic gain at 4 or 5. Anything higher, and ALC would start to reduce power. At those settings, speaking normally would give me 5-7 bars of ALC as recommended in the manual. Several folks have written to me stating that their K3 also behaved similarly and thus required the same amount of mic gain as I've written. Today however, after testing firmware versions 4.17, 4.18, and then reverting to 4.14 I've noticed that mic gain now needs to be set to 15 in order to achieve the same results.

Re: [Elecraft] [K3] Enhancement request - audio mixing
I've been paying close attention to this thread, having purchased the K3 sub-receiver with the intent of using it next Field Day with my two very-orthogonal 40M antennas. My question is, has it been thought through how the capability of having two receivers and two antennas works best in a contest? I sense from this thread that it is distracting to not be able to hear only the chosen antenna in both ears. It makes me wonder, could a different optional mode for the K3's antenna switch help satisfy this wish? Ideas are cheap, and one that comes to mind is this: When listening to two antennas, a TAP of the ANT switch would feed what's in the left ear into both ears. If instead a slightly longer HOLD of the ANT switch was made, what was heard in the right ear would then be fed into both ears, and also select the XMIT antenna. After the contest exchange, any further tap of the ANT switch would revert the receivers to putting their separate signals into each ear, maybe assigning the last active antenna to the left ear. In use in a contest, then, if the desired station were strongest in the right ear, the operator would press the ANT switch for one second, work the station (hearing it in both ears), and finish with one tap of the ANT switch to returned reception to its prior dual-receiver mode. Note that such a mode might be implemented as an option. If set to that mode, then a K3 would enter that mode when the diversity mode was invoked. My post is not a request, but rather a question that, given the power of dual receivers and antenna switching, has the best way to use this capability in a contest been worked out?

Re: [Elecraft] KX1 Kit -- VFO Tuning and Readout ??
Hi Phil, What you are seeing is exactly correct. When you tap the Band switch, you're seeing two temporary displays (MHz, then KHz), then it returns to the normal frequency display for your current tuning rate. So, yes, the numbers change 3 times, but that 3rd time is just the rig returning to it's normal display. This is explained a bit more clearly on page 29, right hand side, 3rd checkbox: You can check the MHz and kHz digits at any time by tapping BAND. For example, if the VFO frequency is 7100.00 kHz, tapping BAND will first show 7, then 100, then return to the appropriate display for your selected tuning rate. 73 -- Joe KB8AP On Nov 11, 2010, at 4:33 PM, Phil Hystad wrote: OK, I think I know what I am reading on the LED display but I need confirmation.

Re: [Elecraft] KX1 Kit -- VFO Tuning and Readout ??
Phil, The frequency display is not always simply MHz and kHz. It all depends ... The final display depends on the frequency resolution that you have set by tapping (or holding) the VFO knob. Consider that the display shows only 3 digits. If you hold the VFO knob down, the display (and the knob resolution) will change to kHz. So what is displayed when you tap the band button is MHz followed by kHz (and nothing more). If you tap the VFO knob to show 1 place behind the decimal, the VFO knob tunes in 100 Hz increments and the display shows those 100 Hz increments. So the display will show something like 32.5 when tuned to 7032.5 kHz. When you tap the BAND button, you will see 7 followed by 032 and then the display will show 32.5. If you tap the VFO knob again, you will be set to 10 Hz increments, and the display will show something like 2.54 (using the example above). Tapping the BAND button will consecutively show you 7, then 032 and finally 2.54. So it really does flash first MHz, and then kHz, but then shows you the greatest resolution that you have set by tapping/holding the VFO knob. In other words, there is an initial display (MHz), then an interim display of the kHz, then a final display which can be either 10 Hz, 100 Hz or 1 kHz depending on the resolution that you have set. 73, Don W3FPR On 11/11/2010 7:23 PM, Phil Hystad wrote: Question For you KX1 experts...

Re: [Elecraft] [K3] Enhancement request - audio mixing
My interest in the audio mixing enhancement is limited to non-diversity use of the subrx, i.e. with main rx on vfoA and subrx on vfoB tuned to a different station. The K3 already provides all the control I need for diversity reception. Barry N1EU K6KV Gary wrote: I've been paying close attention to this thread, having purchased the K3 sub-receiver with the intent of using it next Field Day with my two very-orthogonal 40M antennas. My question is, has it been thought through how the capability of having two receivers and two antennas works best in a contest? I sense from this thread that it is distracting to not be able to hear only the chosen antenna in both ears. It makes me wonder, could a different optional mode for the K3's antenna switch help satisfy this wish? Ideas are cheap, and one that comes to mind is this: When listening to two antennas, a TAP of the ANT switch would feed what's in the left ear into both ears. If instead a slightly longer HOLD of the ANT switch was made, what was heard in the right ear would then be fed into both ears, and also select the XMIT antenna. After the contest exchange, any further tap of the ANT switch would revert the receivers to putting their separate signals into each ear, maybe assigning the last active antenna to the left ear. In use in a contest, then, if the desired station were strongest in the right ear, the operator would press the ANT switch for one second, work the station (hearing it in both ears), and finish with one tap of the ANT switch to returned reception to its prior dual-receiver mode. Note that such a mode might be implemented as an option. If set to that mode, then a K3 would enter that mode when the diversity mode was invoked. My post is not a request, but rather a question that, given the power of dual receivers and antenna switching, has the best way to use this capability in a contest been worked out?

Re: [Elecraft] Lock P3 frequency range independent of K3
I would really like to see something done along this line. It would significantly improve the utility of the pan-adapter. Another possibility would be to move the waterfall along with the pan display and just move in blank data for the missing waterfall data. This would be handy during SO2V contesting when running toward one end of the band segment and SP'ing the whole segment. 73 Jack KZ5A On 11/10/2010 5:57 PM, ga...@gary-gordon.com wrote: This is to support a previous suggestion on the reflector, to allow locking the P3 frequency range displayed despite tuning the K3. The defacto mode of draging and skewing the waterfall makes it unrecognizable, losing track of and tune to a new target QSO up the band. It would seem much easier if tuning the K3 just moved a marker across an unmoving P3 display. My thoughts are towards operating next Field Day, where I might set the P3 to display, say, 7.025 through 7.075 KHz. Of course there would need to be a provision for re-centering the P3, most likely to a round number, not the actual K3 frequency. For example the P3 could re-set its center to the nearest frequency marker at the top of the the P3. As an example, assume a P3 set to a span of 50 KHz, where its 10 markers at the top would then be spaced 5 KHz apart. Assume a K3 is tuned to 7.048 KHz, and the re-center button is pressed. Consistent with the suggestion, then, the center frequency of the P3 would snap to 7.050 KHz, and display a span from 7.025 to 7.075 MHz. Besides the pile-up value another post suggests for this mode, I see it equally valuable for contests and for looking for an ongoing QSO. 73 Gary K6kV __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] KX1 Kit -- VFO Tuning and Readout ??
On page 64, left column (Pushbutton Switch Function), in the middle of the page on the description of the BAND button (single tap). The text reads: [BAND] One tap shows frequency (MHz first, then kHz; L or U is added in LSB or USB modes). Two quick taps selects the next higher band. I think it should read as follows to make it more clear: [BAND] One tap shows frequency: first MHz, second KHz, third display frequency with resolution dependent on setting by VFO tap (or double-tap). ...and so on... What threw me for a loop was that the third display looked to be something unusual since I was not expecting it and I was confused as a result. I now understand how this works but when first confronted by the display of MHz, KHz, and so on I was not expecting three different numbers. 73, phil, K7PEH On Nov 11, 2010, at 5:06 PM, Ron D'Eau Claire wrote: Phil, can you describe where on the page you see where it says there are only two steps to display the frequency?

But, when I tap the BAND button, I get the MHz readout of 7 then I get two readouts following that as 080 and then 80.0 and only on this third number display is the decimal point lit up.

Re: [Elecraft] [K3] Enhancement request - audio mixing
This reply is not speculation. We used orthogonal antennas and dual RX K3's in diversity mode at N4A in the IOTA on Core Banks NC this summer. It worked very well, and we had the high North America island expedition score for LP, beating all but one of the North America HP scores. A pair of three band inverted vees running NW/SE and NE/SW fed with 450 line feed and tuned via a 4:1 balun and the K3 antenna tuners. What happens is that with both RX on that you do not get the nature of signal separation you are expecting. You get phasing separation because the antennas will decode any polarization off pure vertical and pure horizontal into the same kind of separation you have listening to a conversation in a crowded room. Signals not low angle frequently came in on a rotating polarization, moving back and forth from one ear to the other. What was quickly clear was that if we turned off the SubRX, the moving back and forth is converted into rapid deep QSB that defeats copy. The LOUD stations tended more to be in one ear or the other, but those are easy to work. The WEAK signals on 40m particularly, would be affected by this rotating polarity. The same rotation was heard on the band noise, some of the guys having a hard time listening to this rotating background. I was constantly cleanly copying signals that sounded like they were starting on a fadeout but just rotated through my head to the other side instead. One has to hear it to understand it. The complexity you seem to be recommending was unneeded for our best score ever. We knew that to transmit, the predominant signals needed to be in the LEFT ear. The ANT button just toggled that for us. We used the config menu to label one ant NEAST and the other NWEST so that came up on the display when we switched it. This was never a confusion and it was used competently right off the bat by all the operators. You're transmitting to the signal in your left ear. If it's in the right, hit the ANT button. If what's in the right ear is making it hard to hear, just hit the SUB button. Mixing the channels when doing diversity RX seems to me anyway to just muddle it and reduce the benefits. To use the K3 in the way described for N4A requires that the subrx is set up to use the non-TX antenna of the ANT1 ANT2 pair. This of course is not compatible with using AUX for diversity listening on RX only antennas for 160 because that is not internally switched. I have solved that by getting the K3 back panel from Elecraft with the ANT3 BNC hole punched into it, and a miniplug to BNC cord, which I shortened on the BNC end. I used this to bring out the other antenna jack from KANT3 to the K3 back panel at ANT3. Then to do this kind of thing at FD or next year's IOTA just patch ANT3 to AUX RF and leave the SubRX listening on AUX RF. Having used this at N4A, I find NOT having it at home is like something is missing, and I'm designing my station forward to take advantage of it. 73, Guy.

Re: [Elecraft] K3 Firmware
Hi Lyle et all, Sorry for the rapid-fire succession of email from me regarding this, but I've found a way to replicate the issue. I've noticed that when you reduce drive power so that the 10W amplifer is inline, then increasing drive back up to 100W, only 50 watts will initially be produced. Whistling into the mic while this is happening will show the output power slowly creep back up to the full 100W after a few seconds. I've never had this problem until now. I do recall others describing similar issues with firmware back in the 3.XX range. Performing the TX gain calibration does not fix the issue.

Re: [Elecraft] [K2] ALC and power control on 40m SSB in K2/100
Hello Group, Just to complete the loop and to say thanks to Don, Steve and others who contributed to this discussion. I've applied the mod to the KSB2 board - 1k0 resistor in series with the base of Q1 and changing the value of R9. The ALC's can now control the output power of my K2 on 80/40/30m on SSB. I'm very happy. Thanks to everyone for your advice. 73, John VK7JB -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-ALC-and-power-control-on-40m-SSB-in-K2-100-tp5719064p5731296.html Sent from the [K2] mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] OT: K3 vs an RFI noisy furnace

This is unsafe and illegal, because it creates large leakage currents on the green wire. The maximum permitted leakage current on green is 5 mA. One proper way to filter the AC line is with a filter that includes series inductance (usually a common mode choke) and much smaller shunt capacitors. Common mode current on the AC line can also be suppressed using multi-turn ferrite chokes wound on the mains power cable.

Re: [Elecraft] Milt Sullivan, RL Drake Chief Engineer, SK
Milt was a good guy. I believe his title was VP of Engineering when I was there 1976-1979. Even though he was supposed to be an executive at that point he still loved to get his hands dirty. I remember him coming up with creative ideas to solve engineering problems on some designs I was working on at the time. For example, the MN2700 kilowatt antenna tuner required some high-voltage, high-current fixed capacitors. We were quoted a ridiculously high price and a 6-month lead time by the vendor. So we figured out a way to make our own capacitors from Teflon printed circuit board (for low loss / high Q) spray-painted with Q dope to prevent corona discharge. Milt was a realist about project management. He was very aware that engineers have a tendency to try to design everything to perfection, regardless of the schedule or cost. He had a sign over his desk that read, Good enough is better than perfect. Alan N1AL On Thu, 2010-11-11 at 21:02 -0800, Jim Brown wrote: This was in today's ARRL Letter. Milton A.

Sullivan designed and oversaw the designs of all the most significant Drake Amateur Radio products, including the 1A, 2B and 2NT transmitter, all the 4 lines and the beginning of the 7 line. After retiring from Drake in 1984, Sullivan ran his own business selling and setting up satellite television systems, an offshoot of his later projects at Drake that involved designing satellite equipment. After that, he went back to work full time as chief engineer for Lytton Electronics, where he worked until his final retirement in 1990. In 1993, he and his wife Judith moved to South Carolina where Sullivan worked for Alpha Delta, the small company owned by his former Drake colleague and long time friend, Don Tyrrell, W8AD. Sullivan donated his body to science.

Re: [Elecraft] ...RFI ...
Jim... Thanks very much for sending along the link to your article. It is a very nice not-too-technical summary, particularly as it addresses the RFI problem that some of us experience with nearby audio equipment, as well as the function of the green wire. Although not a part of the usual Elecraft submissions, it should be required reading, and I was very pleased to find it on the reflector.
